Lymphoid hyperplasia refers to the enlargement of lymph nodes, which is most commonly caused by bacterial and viral infections. Oral antibiotics such as cephalosporins or ribavirin can be taken, and medications that remove heat and reduce fire such as Andrographis paniculata oral solution can be used to make the enlarged lymph nodes gradually subside. However, there are other diseases that can cause lymphocytosis and enlarged lymph nodes, such as hematologic diseases that require routine blood tests or even bone scans, and if clear, chemotherapeutic drugs are needed. If it is an autoimmune disease, it needs to be treated with targeted drugs and hormones, such as dexamethasone, etc. If it is a parasitic disease, it needs to be treated with anthelmintic drugs. In any case, if the oral medication for enlarged lymph nodes is ineffective, it is necessary to go to the hospital in a timely manner to consult the doctor and determine the treatment plan.
